Enumeration of virtual quandles up to isomorphism
Virtual racks and virtual quandles are nonassociative algebraic structures based on the Reidemeister moves of virtual knots. In this note, we enumerate virtual dihedral quandles and several families of virtual permutation racks and virtual conjugation quandles up to isomorphism. We also classify virtual racks and virtual quandles up to order 8 using a computer search. These classifications are based on the conjugacy class structures of rack automorphism groups. In particular, we compute class n…

TIL: Anfang der 1990er gab es unter dem Namen „Piazza Virtuale“ ein Kunstprojekt im Rahmen der damaligen Documenta, das Möglichkeiten des interaktiven Fernsehens erforschte und ausprobierte. Plattform war damals 3sat, Rundfunkbeitrag bei der Arbeit. Das Projekt wurde vor wenigen Jahren wissenschaftlich nachbereitet. Wenn ihr auch darüber lernen möchtet, empfehle ich zum Einstieg den zugehörigen Golem-Podcast:

Der Experimental-TV-Sender, der 1992 für kurze Zeit ein europäisches soziales Netzwerk aufspannte, ist fast vergessen. Wir wollen das im Podcast ändern.

Are you looking to accurately measure your organisation's current progress on the path towards digital transformation?
Take the OAV Maturity Model survey!
Developed by the Network eAcademy team of the GÉANT project, it’s designed to help #NRENs and R&E organisations assess where they are on their Orchestration, Automation, and Virtualisation (OAV) journey, and map out the next st…

Orchestration, Automation and Virtualisation (OAV) Maturity Model: a tool to assess where you are and help you reach the next level | GÉANT CONNECT Online
Words: Maria Isabel Gandia Carriedo (CSUC) and Eldis Mujaric (CARNET) Organisations with advanced capabilities in Orchestration, Automation and Virtualisation (OAV) are more likely to succeed in their path towards digital transformation. But how can the progress in these areas be accurately measured? And how can organisations identify the actions needed to drive further advancement? Maturity Models

Im letzten Teil meiner Serie zu Wegwerfnummern habe ich virtuelle Nummern, Profi-Tools und Reise-SIM getestet.
Und dabei etwas erstaunt festgestellt, dass man mit Kryptowährung einfach so eine funktionierende österreichische Handynummer bekommt. Ohne Identitätsnachweis, ohne Name, ohne E-Mail-Adresse. Aus Singapur. 🤔

Low Overhead Allocation Sampling in a Garbage Collected Virtual Machine
Compared to the more commonly used time-based profiling, allocation profiling provides an alternate view of the execution of allocation heavy dynamically typed languages. However, profiling every single allocation in a program is very inefficient. We present a sampling allocation profiler that is deeply integrated into the garbage collector of PyPy, a Python virtual machine. This integration ensures tunable low overhead for the allocation profiler, which we measure and quantify. Enabling alloca…

Centre driven Controlled Evolution of Wireless Virtual Networks based on Broadcast Tokens
In a wireless sensor network, the virtual connectivity between nodes is a function of the keys shared between various nodes. Pre-embedding these key configurations in the nodes would make the network inflexible. On the other hand, permitting subsets of nodes to engage in a common key synthesis phase to create secure distributed connections amongst themselves, would decouple and conceal the information flow from the controlling centre. An intermediate solution is the notion of a centre driven ke…
